Improved journal-box



- UNITED STATES a PATENT -OFFICEQ HENRY A. LEE OF WORCES'J.ER,-MASSACHUSTTS.

IMPRQV,ED JOU RNAL-BOX.

Spec itieation forming part of Letters Patent No. 49.124; dated August1, 1865.

To all whom it may concern:

Be it known that I, HENRY A. LEE, of the city and count y of W0rcester,and State of Massachusetts, have invented certain new and usefulImprovements in Journal-Boxes; and I 'do hereby declare that thefollowing isa full; clear, and exact description of the constrnc-nerosssection through th e'samer Fig. 3 represents a vertical sectionthrough line a b of Fig. 2. To enable others skilledin the art to makeand use my inveutiou, I j x'vill proceed to describe its constructinahd'operation.

A represents the upper'half or shell of my journal-box, and B the lowershell.

0 represents the screws by means of which the upper part is sechred tothe lower part when the bearing of a shaft has been properly adjusted inthe latter. The general construction of the two parts does not differmuchfrom those used heretofore.

D represents four set-screws, two on each of the flanges c of the upperpart, A. They are screwed into suitable holes in said flan ges, andtheir blunt ends rest upon the upper faces of the flanges d ofthelower'shell,B. By means of these set-screws the upper shell, A,, canbe so adjusted asto leavea space between the two shells, as representedin the,drawings, and tle i'astening-screws C canbe turned tight toprevent them from becoming loose.

The advantage of this arraugemznt is obvi- 'ous,fbr;it is very difficultto make such atiaecuratefitof the shells-of the journal-box that thebeuring of the shatt willru1iperfecth true, and when the upper shell isscrewed down tight it may either cause too much friction or. the beariugmuy have too much play; By,the use of the setscrewsD the uppershell, A.con be adjsted upon the lower to make a perfect (it, and then thefastening.sctew Qc:1n .be tightened much as desired to prevent them fromworking loose. Again,atter the shaft has W01ll out the bearing allthati's necessary is to let down the upper shell, A, by means of thescrews D, to

fitthe bearin g si1ugly,aud thetasteuing-screpv5 C are again tightened,and thusan eflicieut;

deviceis presented to manufacturers to avoid the many annoyances arisingfrom the rapid i wearing out of journahboxes.

It is evident*that in some cases, tere it is diflicult to get at theupper side or shell of the box. said set-screws maybe applied to thelo\v.- er shell in the same mauner and for the same purpose. f

Having thus fully described the nature of. my invention,what I claimherein as new," and desire to secure by Letters Patent, is

The application to journalboxes of the setscrews D, within one of theshells or halves of which the journal-box is coniposed, substantially inthe manner and lor the purposes specifred.
